Transcriptional repressor NIR functions in the ribosome RNA processing of both 40S and 60S subunits. [PDF]
BACKGROUND: NIR was identified as an inhibitor of histone acetyltransferase and it represses transcriptional activation of p53. NIR is predominantly localized in the nucleolus and known as Noc2p, which is involved in the maturation of the 60S ribosomal ...

A new sexannulate species of Orobdella (Hirudinea, Arhynchobdellida, Orobdellidae) from Kii-Oshima Island, Japan [PDF]
A large-type sexannulate leech species, Orobdella ibukifukuyamai sp. nov., from Kii-Oshima Island, Japan, is described based on morphologic and molecular data. Phylogenetic analyses using nuclear 18S rRNA, 28S rRNA, histone H3, mitochondrial cytochrome c

With an exception of aphids, insects’ 28S rRNA is thought to harbor a “hidden break” which cleaves under denaturing conditions to comigrate with 18S rRNA band to exhibit a degraded appearance on native agarose gels.

Nucleotide sequence of the region between the 18S rRNA sequence and the 28S rRNA sequence of rat ribosomal DNA [PDF]
The DNA sequence of the intragenic region of the rat 45S ribosomal RNA precursor was determined. This sequence contains 2282 nucleotides and extends from the conserved EcoR I site near the 3' terminus of 18S rRNA to 69 nucleotides downstream of the 5' terminus of 28S rRNA.

Selection and evaluation of potential reference genes for gene expression analysis in Avena fatua
Eight commonly used candidate reference genes, 18S ribosomal RNA (rRNA) (18S), 28S rRNA (28S), actin (ACT), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), elongation factor 1 alpha (EF1α), ribosomal protein L7 (RPL7), Alpha-tubulin (α-TUB), and TATA ...

A troglobitic species of the centipede Cryptops (Chilopoda, Scolopendromorpha) from northwestern Botswana [PDF]
A new species of Cryptops, C. (Cryptops) legagus sp. nov., occurs in caves in the Koanaka and Gcwihaba Hills in northwestern Botswana. Bayesian molecular phylogenetics using 18S rRNA, 28S rRNA, 16S rRNA and cytochrome c oxidase subunit I corroborates a ...

We present a secondary structure model for the entire sequence of mouse 28S rRNA (1) which is based on an extensive comparative analysis of the available eukaryotic sequences, i.e. yeast (2, 3), Physarum polycephalum (4), Xenopus laevis (5) and rat (6).

The sequences of 18S and 28S rDNAs have been used as molecular markers to resolve phylogenetic relationships of Heteroptera for two decades. The complete sequences of 18S rDNAs have been used in many studies, while in most studies only partial sequences ...

Effect of 2′-O-methylation on the structure of mammalian 5.8S rRNAs and the 5.8S—28S rRNA junction
The mammalian 5.8S rRNA contains a partially 2'-O-methylated uridylic acid residue at position 14 which is largely or entirely methylated in the cytoplasm (Nazar, R.N., Sitz, T.O. and Sommers, K.D. (1980) J. Mol. Biol. 142, 117-121). The effect of this methylation on the 5.8S RNA structure and 5.8-28S rRNA junction was investigated using both chemical ...

Evidence on the conformation of HeLa-cell 5.8 S rRNA during interaction with 28 S rRNA
The sites and extents of bisulphite-mediated deamination of cytidine residues in HeLa-cell 5.8 S rRNA within the 5.8 S / 28 S rRNA complex have been determined. Comparison of these data with equivalent data for isolated ('unbound') 5.8 S rRNA suggests that the conformation of several cytidine residues, including inter alia those within the 5'- and 3 ...
